Introduction

GlobalViewer Enterprise (GVE) is a powerful software tool that allows the user to monitor and control a large AV system.

Over time, large numbers of log files are created and stored on the database server, occupying memory and, eventually, slowing the server. This guide provides information about a script that can be run to clean up the database. The script carries out four functions:

1. Clears logs

2. Re-indexes tables

3. Updates statistics for tables

4. Defragments tables

About the Script• You must be a System Administrator or have ownership of the database to run the script.

• The script works with GVE versions 2.4 and later.

• This script works with SQL Server versions 2012 and later

• In this guide, comments are shown in the left column. The script is shown in the right column.

• If required, users can copy and paste the script into Notepad. Save the file as GVE_DB_maint.sql.

• Extron recommends running it every 3-6 months, depending on the size of the system.

Running the Script1. Back up the Database.

2. Turn off all services and IIS.

3. Run the script, using the following command:USE MASTER

GO

EXECUTE dbo.dba_indexDefrag_sp @DATABASE='GVE'

NOTE: Change the database name, if it is not GVE.

The script takes 2-3 minutes to run.

4. Shrink the database.

a. In Windows Explorer, navigate to the database.

b. Right click on the database name (GVE by default).

c. In the drop-down list, click Tasks.

d. In the drop-down list, click Shrink.

e. In the drop-down list, click Database.

Author: Michelle Ufford, http://sqlfool.com

Purpose: Defrags one or more indexes for one or more databases

Notes:

CAUTION: TRANSACTION LOG SIZE SHOULD BE MONITORED CLOSELY WHEN DEFRAGMENTING. DO NOT RUN UNATTENDED ON LARGE DATABASES DURING BUSINESS HOURS.

@minFragmentation defaulted to 10%, will not defrag if fragmentation is less than that @rebuildThreshold defaulted to 30% AS recommended by Microsoft in BOL; greater than 30% will result in rebuild instead

@executeSQL 1 = execute the SQL generated by this proc; 0 = print command only

@defragOrderColumn Defines how to prioritize the order of defrags. Only used if @executeSQL = 1. Valid options are:


range_scan_count = count of range and table scans on the index; in general, this is what benefits the most FROM defragmentation fragmentation = amount of fragmentation in the index; the higher the number, the worse it is page_count = number of pages in the index; affects how long it takes to defrag an index

@defragSortOrder The sort order of the ORDER BY clause. Valid options are ASC (ascending) or DESC (descending).

@timeLimit Optional, limits how much time can be spent performing index defrags; expressed in minutes.

NOTE: The time limit is checked BEFORE an index defrag is begun, thus a long index defrag can exceed the time limitation.

@database Optional, specify specific database name to defrag; If not specified, all non-system databases will be defragged.

@tableName Specify if you only want to defrag indexes for a specific table, format = databaseName.schema.tableName; if not specified, all tables will be defragged.

@forceRescan Whether or not to force a rescan of indexes. If set to 0, a rescan will not occur until all indexes have been defragged. This can span multiple executions. 1 = force a rescan 0 = use previous scan, if there are indexes left to defrag

@scanMode Specifies which scan mode to use to determine fragmentation levels. Options are: LIMITED - scans the parent level; quickest mode, recommended for most cases. SAMPLED - samples 1% of all data pages; if less than 10k pages, performs a DETAILED scan. DETAILED - scans all data pages. Use great care with this mode, AS it can cause performance issues.

@minPageCount Specifies how many pages must exist in an index in order to be considered for a defrag. Defaulted to 8 pages, AS Microsoft recommends only defragging indexes with more than 1 extent (8 pages).

NOTE: The @minPageCount will restrict the indexes that are stored in dba_indexDefragStatus table.

@maxPageCount Specifies the maximum number of pages that can exist in an index and still be considered for a defrag. Useful for scheduling small indexes during business hours and large indexes for non-business hours.

NOTE: The @maxPageCount will restrict the indexes that are defragged during the current operation; it will not prevent indexes FROM being stored in the dba_indexDefragStatus table. This way, a single scan can support multiple page count thresholds.

@excludeMaxPartition If an index is partitioned, this option specifies whether to exclude the right-most populated partition. Typically, this is the partition that is currently being written to in a sliding-window scenario. Enabling this feature may reduce contention. This may not be applicable in other types of partitioning scenarios. Non-partitioned indexes are unaffected by this option. 1 = exclude right-most populated partition 0 = do not exclude

@onlineRebuild 1 = online rebuild; 0 = offline rebuild

@sortInTempDB Specifies whether to defrag the index in TEMPDB or in the database the index belongs to. Enabling this option may result in faster defrags and prevent database file size inflation. 1 = perform sort operation in TempDB 0 = perform sort operation in the index's database


@maxDopRestriction Option to specify a processor limit for index rebuilds

@printCommands 1 = print commands to screen; 0 = do not print commands

@printFragmentation 1 = print fragmentation to screen; 0 = do not print fragmentation

@defragDelay Time to wait between defrag commands; gives the server a little time to catch up

@debugMode 1 = display debug comments; helps with troubleshooting 0 = do not display debug comments
